I just bought my first finger flasher last week
http://www.emagictricks.co.uk/product_i ... ts_id=1314 £12.40 which I love.
What I really love of course is the effect. The flasher can only fire once before needing reloading & you can't really do much trick wise while you have it on. Also it's not that easy to slip on in your pocket as like a ring you need to get it in place.
So my first thought is one on a pull might be better.
There seem to be many kinds of flashers out there so could you kind folk who have some give some details & links to them.
I imagine there must be a flasher that works from gas, thus can have multiple fires before a refill is required.
Would appreciate any views. Ta
